Side-frame construction.



ber .is provided with depending To all whom it may concern.

Be it known thatvl, OswALD S. Fumar/lana resident of Pittsburg, in thecounty of Allegheny and .State of Pennsylvania, have vinvented certainnew and. useful Improvements in 'Side-FrameConstruction, of which thefollowing is a specification.

An object of my invention is to provide a new and improved car truckside frame preferably made of cast steel and. comprising separable topand bottom members and separable columns or column castings.

A further object of the present invention is to provide a new andimproved combined side frame and journal-box construction havinginterlocking members.

'l n the accompanying drawing, which illustrates applications of myinvention Figure l a part vertical sectional View and a part elevationalview of a side' frame construction embodying my invention; Fig. 2, apart plan and a part sectional view, the section being taken onlinelli-.II of Fig.. l; Figs. 3 and 1i, vertical sectional viewsrespectively taken on lines lll-lll and IVIV of F ig. 1,' Fig. 5, aperspective view of spring seat casting; Fig. 6, an elevationalA viewVof a modified form from that shown by Fig. l; Fig. .7, a plan of theform ofFig. 6; and Figs. 8 and 9, detail perspective views of theinterlocking means for the lower member' of the side frame and thejournal-box.

Referring to the drawing and as preierred the car `truck 'side framecomprises illustrated bythe form of Fig.' 1, a separable top-member l,and a separable 'bot` tom member 2. -These members are made ot caststeel and may be of any desiredcrosssection. The top or arch member lateach end thereof is formed with an engaging or interlocking.member 3adapted to coact with' a member formed on an independent journalboX5 forlocking said parts togetheri ln addition to the members 3 thetop-'memmembers 6 each having an inclined bearing face 6a and' with lugs7. Lugs 7- are preferably'wedgeshaped and are designed to engage thecolumns 8 ofthe side frame.

The bottom or inverted. arch member Elf has its ends l'crmed withengaging members hdesi,ojo/ed. to cooperate with members formed on thesides of the journal-boxes, as shown, 'the engaging members of thebottom side .iframe 'member each comprises a hooked- SIDELFRAIVLECONSTRUCTION.

shaped member 9 adapted to enter a pocket l() formed on a side of eachjournal-box, but I do no t desire to be limited to the ,exact form ofinterlocking means shown. Membei' 2 is also provided with lugs lladapted1 to engage inclined member seat or column'casting. l. y

In the form of Fig. 1the spring seater column-casting comprises the twocolumns 8 and the sprin L gral structure with the u columns havinglaterally projecting flanges` 14 each having an inclined face 15 respectively adapted, when the parts are asseml l f l bled, to engage a lug 7ofl the top-membei of the side frame. After the topmember is placed inposition, the ends a of thejournal-box engaging member 4 are turned downover the edges of the member 3 of the` top- Mmember as thus preventintopfmemb By the abled to g any lateral movement ofthe er on thejournal-box. i

construction illustrated, I, am endispense with bolts or rivets forlocking the parts together, but if it -is found desirable to bolt orrivet the spring lseat casting' to the top or bottom member Ior boththis may be done.

In the form of Fig., G, the spring seat 13a is .formed integral with thelower member 2a, but the columns 8a are separable and are inter-lockedwiththe top and bottom members in substantially the same manner as shownin the form et' Fig. l..

. In the form of Fig. 6, I omit the contacting members'G from thetopmember la and provide a slightly different connection between thebottom member 2 and the journal-hox. The coacting interlocking means torthese parts are particularly shown by Figs. 8 and 9, and comprise themember 9 formed on the member 2f and the pocket l0 of the journal-box5a. The wall 101 is formed with small projections l()c adapted when themember 9a ted in the pocket,

is in'ser to be turned down over the same, and prevent tlie member 2afrom moviug'vertically with respect to the pocket. y

What .I claim is ze l. A car truck ,side frame consisting-.of separabletop and bottom members each hav ing means for engaging an independentjouinalnbox, andl a separable ,interlocking column connecting the topand bottoml members.

8. The combination with acar truck side frame comprising separable topand bottom members, of an independent journal-box, said top and bottommembers andthe journal-box having interlocking means for securing thejournal-box to the side frame, and a column connecting the top andbottom members.

9. The combination with a car truck side frame comprising separable topand bottom members, of an independent journal-box, said top and bottommembers and the journal-box having interlocking means for securing thejournal-box to the side frame, and a separable springseat castingcomprising a column, said column connecting the top and bottom members.

10. The combination with a car truck side frame comprising separable topand bottom members, of an independent journal-box, said bottom memberand the journal-box having coacting interlocking means, and a columnconnecting the top and bottom members.

11. The combination with a car truck side frame comprising separable topand bottom members, of an independent journal-box, said top member andthe journalbox having coacting interlocking means, anda columnconnecting the top and bottom members.
